Astronomers Identify Possible Dyson Sphere Candidates

Astronomers have identified seven potential candidates for Dyson spheres, hypothetical alien megastructures designed to harness a star's energy, within 1,000 light-years of Earth. These candidates, all M-dwarf stars, exhibit excess infrared radiation, a possible signature of such structures. However, natural explanations like gas and dust discs cannot be ruled out. While the concept of Dyson spheres is intriguing, the feasibility of their construction remains highly speculative due to the immense material and energy requirements.
